【Abstract】 The prestack depth migration is an important technique to prove complicated geologic structure because that it has overcome the limitations of general processing. The Kuitunnan anticline lies in the third row of structural zone in the southern margin of Junggar basin. It is difficult to credibly prove the structure with general processing seismic data due to the complex geologic condition and the large changing of transverse stratum velocity in the piedmont. The Kuitunnan anticline is credibly proved with prestack depth migration and the drilling has shown a good effect.更多还原
